Bias for Jolida 502 P Amplifier

I went with a KT88 Gold Lion tube package specific for the 502 by Upscale Audio in CA. Cant rec it highly enuff Check out the website - they ship. Improvements across every aspect of performance.

Do Gold Lion KT88s sound better than KT120s in a 502? I think they LOOK better for sure, but I've been putting off buying a set.

In my opinion the kt120's sound much better in the 502p.The 120's are more extended top to bottom with with better separation and a fun energetic presentation .The Gold Lions have less extension top to bottom and seem just ever so slightly congested when compared to the 120's the GL just seem more laidback and relaxed. FYI I had the gold lions in for the last 6 months and the 120's for about a month now.

Man all this talk about the KT-120s makes me want to put them back in my Jolida 502P. That or check out the PSVane KT-120s. They are pretty looking. Anyway I've been enjoying the music in a nearfield set-up for the past couple of months with JJ KT88 Blue Glass tubes, JJ 5751 tubes and Mullard CV4024s.

I have to look through my notes. One tube enthusiast by me strongly preferred the solid plate Penta Labs KT88SC vs the Gold Lion KT88s. I think he liked them better all around and the Penta Labs KT88s had better reliability in his experience.

I called Jolida the other day wondering about why my 502P has 3 screw holes on the sides with no screws. The guy I talked to (not Jarred forgot to ask the name) said those are for the tube cover (didn't know one was available) anyway while talking I asked him about using KT 120's and he said he didn't care for the sound because he found them a bit bright but that the KT150's were really sounding nice (if one could afford them...)

My amp came with the Tungsol 6550 and it's sounding just wonderful as it settles in. Really liking the 3d solid soundstage and great bass. Lush but detailed at the same time. The proverbial discovering all sorts of new things in well known recordings taking place frequently . Paired with my Mapletree preamp it seems an exceptional synergistic combination.

You all don't know how much I worried about going from a very powerful SS amp (CJ MF2300A) to a tube amp a quarter of the power, particularly with my Magneplanar 1.7's. I worried for nothing.
